I don’t know anyone that works at Meta, so I’m hoping that someone here could answer this for me- What makes employees there feel good (or at least okay) about doing stuff like this? You're spying on people, no? Surveilling ordinary people, not enemy combatants or foreign militaries? Perhaps a friend of a friend or even a family member? This kind of thing is so creepy and disturbing to me, not that it’s anything new…
Would someone explain in plain language what is wrong with an app listening on a port for messages from the browser? It seems like a helpful asynchronous method to maintain state between browser and app.
